IPC: G06F3/12
Filed: 1996-08-23
Abstract: PROBLEM TO BE SOLVED: To achieve a higher processing in converting characters, capable of automatically eliminating data not to be reused among data in a font cash. SOLUTION: When a CPU 1 receives document data from a host W/S 7 described in the PDL, it forms a bit map image in a frame buffer 5. For a character appeared for the first time, the CPU 1 converts the character to bit map data, and stores the data in a font cash 4 corresponding to the attribute of the character. On the other hand, for a character, which has been converted to bit map data, the bit map data corresponding to the character are read from the font cash 4 and written in a frame buffer 5. Whenever processing for one page is completed, the bit map image is transferred to a printer engine 10 for printing. Furthermore, when processing for the entire document data is completed, the bit map image of a character temporarily used is retrieved based on the attribute of the character stored in the font cash 4 so as to be eliminated from the font cash 4.
